WSGIWAPI makes it easy to build web APIs, without dealing with the details of HTTP. You simply define a hierarchical tree of URL components, with callables as the leaves of the tree, and WSGIWAPI does the work of making this into a WSGI application.

WSGIWAPI also provides some additional features, such as automatic documentation support for your API and parameter validation.
